'some cases it has proven of great advantage to cut the screen material in strips about one (l) foot in Width, which are laid across the belt and secured by Wiring. This method is preferable Where heavy screen material is used, .for the reason that the screen sections are bent more or less in passing over the drums, and when secured as here described, would not need to straighten out in passing on the straighj stretch from drum to drum, as all straingi'ind weight is taken up by the cables.

The lower drum 2 may be let into va recess le in the flume so as not to deflect or d. turb the current flow in the flume. On the up stream side 0i ,the drum may be placed flexible narrow` strip 18 of any suitable material. bottoinof the flume, and keeps fish from getting down under the drum and yet will swing up and let any little stick or other material which may happen to stick into the screen pass up by. It is obvious'that similar strips not here shown may be .laced on the sides of the screen to serve tie same purpose.

The apparatus is simple in construction, prompt and .reliable in action, and takes no more space than other screens.

The material and finish of the several parts of the apparatus are Such as experiand yndgrnent of 'ne manufacturer may metete.

This is secured to the I Wish it understood that varouschanges in foi-Vm, proportions and minor details of construction may be resorted to Within the scope of the appended claim, and that I do not wish to limit myself to the specific design and construction here shown.

Having thus described 1nyinvention,what I claim and desire to secure by Letters Patent, is-

A fish screen attachment for flumes and the like, including a flume, journaled flanged drums located, one beneath the surface of the flowing water, and the other aboye the flume and in advance of the first .named drum, an endless belt fitted to said drums, means by which the drift material elevated by the belt may be transferred to the nume beyond the belt, and means to produce an intermittent movement of the belt, said means including a current wheel journaled in the flume beneath the upper belt drum, and having a crank in its shaft, a slidably guided connecting rod having a paWl pivoted to its upper end, and a ratchet Wheel upon the upper drum shaft, with which the pawl engages at each reciprocaton' of the rod.

In testimony whereof I have hereunto set my hand in the presence of tWo subscribingr witnesses.
